# Figuring out what is the USB stick
|
||||
|
||||
Start by mounting the stick which should be automatic in GUI.
|
||||
|
||||
```
|
||||
mount|grep /dev/sd
|
||||
```
|
||||
|
||||
should tell what is the /dev/USBSTICK
|
||||
|
||||
## Creating bootable USB stick
|
||||
|
||||
```
|
||||
isohybrid image.iso
|
||||
dd if=image of=/dev/USBSTICK bs=1024
|
||||
```
|
||||
|
||||
## Creating .iso from CD/DVD
|
||||
|
||||
First unmount the CD/DVD and then
|
||||
|
||||
```
|
||||
dd if=/dev/DRIVE of=image.iso
|
||||
```
|
||||
|
||||
DRIVE can be /dev/dvd /dev/cdrom or /dev/scd0 depending on the CD/DVD.
|
||||
|
||||
## Backing up scratched CD/DVD
|
||||
|
||||
```
|
||||
dd if=/dev/DRIVE (see above) of=IMAGE.iso conv=noerror
|
||||
```
|
||||
|
||||
maybe ddrescue should be used instead of dd.
